<p>The unit (6) has a distal end (6b) and a proximal end (6a), where the proximal end is oriented remotely from a supply chamber (2) during usage. The proximal end has an opening ring that is arranged such that distance between two opposite edges of the proximal end is greater than internal diameter of an internal channel. The opposite edges are arranged on both sides of a longitudinal axis (L). A set of gripping zones is placed on both sides of the longitudinal axis. An independent claim is also included for an implantable device.</p> |
